Issue while installing dependencies (mac os 12.3.1, Blender 2.9.3)

[inqtel]

I get the following error message when trying to get the add on to install dependencies. I have mediapipe etc already installed. Per the instructions, I opened blender in admin mode through sudo command in terminal. Watching the progress there, it looked like finding/installing modules wasn't actually the issue, the error seems to come afterwards?

I'd love to get this add on working!!

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:

1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

Error message in last 5 lines are same with me when I first enable addon option block each time

Are you using the intel version of blender? (There's a silicone and a intel version downloaded at blender.org)

It seems like there is an issue with the mediapipe module. First make sure you are using the intel version. Secondly I'd try to delete the mediapipe module in the site packages and reinstall it. I'll try to reproduce this error soon.

[inqtel]

Yes it's the intel version (it's this file, and the platform–support.txt file in library/application support reads “{Intel Inc./Intel(R) HD Graphics 6000/4.1 INTEL-18.5.8}=SUPPORTED”).

I've deleted mediapipe from the site packages folder contained within blender's package contents, and then reinstalled the BlendarMoCap addon (BlendArMocap-release-v141.zip). As before, terminal shows the modules installing, and "Installation process finished" is displayed. Then the traceback error.

Thanks for looking into this!

[cgtinker]

Google recently updated their protobuffers and mediapipe didn't include the change in their dependencies. I've been working on a fix but only tested on windows so far - https://github.com/cgtinker/BlendArMocap/tree/development.

Please try the development build and refer to #56
